The music played inside the Ant Hill of Mumbo's Mountain is a slowed down version of what was originally intended to be the world's main theme. The original theme was partially inspired by the Baby Elephant Walk tune from the film "Hatari!".

The theme that was used for the world Treasure Trove Cove was also the second version that the game's composer, Grant Kirkhope, had written due to the change of the game from "Project Dream" to "Banjo-Kazooie".
